LD7520 controller equivalent, smart green-mode pwm controller.
The protection functions include cycle-by-cycle current limit, OVP, OTP, and OLP. It provides the users a high efficiency, low external component counts solution for AC/.
Furthermore, to satisfy various protection requirements, both latch-mode protection and auto-recoverable protection can.
The LD7520 is a low startup current, current mode PWM controller with green-mode power-saving operation. The SOP-8/DIP-8 package integrated functions such as the leading- edge blanking of the current sensing, internal slope compensation, line compens.
